What things do I need to know before I jailbrake.

I read the post below "how do I upgrade my baseband" and I want to know what is the baseband version of my phone. Where do you find that info. I was asking because I would like to jailbrake my phone and I wanted to find out everything about my phone so I don't have any issues when I JB. Is there anything else I might need to know before I proceed with the JB? I searched out some of the cyndia apps and am looking forward to using them, can't wait till I can get them. My phone is a black iPhone 4 8gb (Sprint) and I have a windows PC running Vista, I believe my phone is locked but am no sure. Is there anything I need to know before I proceed with a jailbrake. Any suggestions will be greatly appreciated.

You don't need to be concerned with the baseband at all. It is only important to people who need to unlock their phones to use with an unofficial carrier such as T-Mobile. The Sprint phones can't be unlocked anyway so it is irrelevant in your case.

Just make sure you create an iTunes or iCloud backup before you jailbreak.
